Description
Technical field
The invention belongs to arid area ecological restoration technical field more particularly to a kind of arid area vegetation implantation methods.
Background technology
Desertification of land, soil erosion and environmental degradation have become influence the key of human social and ask
Topic, world land ccd area account for about 30% or so of the land gross area, and along with environment be constantly destroyed and people
The frequent activities of class and constantly aggravate.China is one of the country of desertification in the world and severe water and soil erosion, at present desert, dagger-axe
Wall and sandy land are 165.3 ten thousand square kilometres total, are related to 18 provinces (area) and 471 counties, account for about the 17% of national territorial area.Soil
Land resource has not only greatly been corroded in ground desertification, makes valuable arable land, the further atrophy in grassland, and bring serious ring
Border problem such as constantly wreaks havoc the Sand-Duststorm of northern China in recent years.Desertification of land problem make the living space of the mankind by
To seriously threatening, continuous with national strategy to develop western regions promotes and the increase of desertificated area infrastructure construction, right
The active demand improved the ecological environment and also more and more strong to the technical need of Novel planting and revegetation.
China western part and " three Norths " (northwest, northeast and North China) most area are in arid and semi-arid lands, precipitation
Amount less, evaporation capacity it is big, the survival rate of planting is low, revegetation difficulty is big.Especially Inner Mongolia Autonomous Region of the upper reaches of the Yellow River
Equal areas, due to drought, vegetation cover degree and plantation survival rate are low, not only cause a large amount of dusts storm, form sandstorm weather, also
Cause serious soil erosion.
Currently, the primary abatement method of desertification and soil erosion is biological method.However, these areas usually soil is husky
Change serious, poor water retention property, and belong to arid and semi-arid lands, water consumption is big but planting survival rate is low, revegetation
Difficulty is big.Thus, there is an urgent need to develop a kind of arid area vegetation implantation methods.

Urethane；Liquid EVA or liquid polyurethane, which penetrate into, is formed by curing impervious barrier in soil.
Further, the concentration range of the liquid EVA or liquid polyurethane is 5%~15%.
Further, the pollutant sorbing material includes activated magnesia, zeolite and gypsum；
The mass ratio of the activated magnesia, zeolite and gypsum is 100：(1~100)：(1~100).
Further, the thickness range of the pollutant adsorption layer is：1~5cm.
Further, the preparation method of the mud granulizing is：Municipal dewatered sludge, gypsum, cement and water-retaining agent are mixed
It closes, mud granulizing is obtained with after secondary granulation processing by being once granulated, the particle size range of the mud granulizing is 0.01~
1cm。
Further, the municipal dewatered sludge, gypsum, cement and water-retaining agent mass ratio are 100：(1~100)：(1~
100)：(0.1~1).
Further, the thickness range of the overburden layer is 10~20cm.
Further, the vegetation includes two or more arbitrary combinations in cold-resistant drought-enduring arbor, shrub and grass.
The municipal sludge of a kind of arid area vegetation implantation methods of the present invention, use is handled by secondary granulation, and is added
Water-retaining agent, improves the water conservation water-holding capacity of soil, and required moisture is provided for plant growth, greatly improves vegetation plantation survival
Rate and increment；It prevents moisture from spreading around by the antiseepage of plantation hole side wall, preserves nutritional ingredient, improve water-holding capacity；
The pollutant of bottom adsorbs, and prevents pollution of the sludge to ambient enviroment；Construction technology of the present invention is simple, without large scale equipment and greatly
Material is measured, it is at low cost, it is suitble to scale application.
